Hi Shiza.
The Colossal 12 hour stay kajal didn't work for me as well, it is mentioned that it is waterproof and smudge-free, but that's simply not the case, plus the colour also keeps on fading within time.. mine stays on for maximum 4 hours and the colour keeps on fading.
I started using it on my lower lash-line instead of the waterline, and that gave me better results than using it on the waterline, how about you try it this way too?
